More than 20 years ago, Tanner [Ann. NY Acad. Sci. 89, 752 (1961)] noted that observers
asked to detect a signal act as though they are uncertain about the physical characteristics …

This paper reports on the results of a survey of user interface programming. The survey was
widely distributed, and we received 74 responses. The results show that in today's …

(I) Encoding of the third dimension (2) Time to collision (TTC)(3) Image segmentation (4)
Motion as a proprioceptive sense (5) Motion as a stimulus to drive eye movements (6) …

We present an independent Gabor features (IGFs) method and its application to face
recognition. The novelty of the IGF method comes from 1) the derivation of independent …

We determined contrast thresholds for lesion detection as a function of lesion size in both
mammograms and filtered noise backgrounds with the same average power spectrum …

Efficient categorizations of complex visual stimuli require effective encodings of their
distinctive properties. However, the question remains of how processes of object and scene …

Retinal ganglion cells, the integrative-output neurons of the retina, can be sorted into
functional classes. In the cat, two ganglion cell classes are labelled X and Y. These are …

Many philosophers doubt that one can provide any successful explanation of sensory
qualities—of how things look, feel, or seem to a perceiving subject. To provide such an …

We present a novel descriptor, called spatio-temporal Laplacian pyramid coding (STLPC),
for holistic representation of human actions. In contrast to sparse representations based on …

The construction of directionally selective units, and their use in the processing of visual
motion, are considered. The zero crossings of∇ 2 G (x, y)∗ I (x, y) are located, as in Marr & …
